"PKL Services [of] Poway, California, has been awarded a $495 million… contract for Royal Saudi Air Force F-15 S&SA type aircraft maintenance upgrade training," the Defense Department said on Thursday.

The announcement noted that the contract is 100 percent foreign military sales to Riyadh.

The Royal Saudi Air Force maintains the third largest fleet of F-15s in the world after the US and Japanese air forces. Saudi F-15s have been involved in the controversial bombing of Houthi rebels in Yemen, generating major civilian casualties.
